How To Test Your Deer For CWD This Hunting Season

*MADISON, Wis.* – The Wisconsin Department of Natural Resources (DNR) reminds hunters that they play an important role in the continued efforts for Chronic Wasting Disease (CWD) surveillance and management in Wisconsin. One of the most effective tools for monitoring CWD is testing your harvested deer, and testing is available statewide.

The DNR is especially interested in receiving more samples from the 2025 Fall Priority Areas [ [link removed] ] near recent CWD detection locations. Additional samples in these areas will help the DNR better understand disease levels and distribution. 

CWD is a contagious, fatal neurological disease that affects the nervous system of deer, elk, moose and caribou. It belongs to the family of diseases known as transmissible spongiform encephalopathies or prion diseases. Prions are misshaped proteins that can spread the disease through direct animal-to-animal contact or in the environment through bodily substances or the carcass of infected deer.

Prions are extremely resilient and capable of remaining in the soil for years, potentially infecting several deer from a single source. Common signs of infected deer in the later stages of the disease are drastic weight loss, drooped head and ears, loss of coordination, excessive salivation and reduced fear of humans.

*How To Test Your Deer*

Any hunter in the state may choose from the following testing options:


* *Self-service kiosks, open 24/7: *Kiosks contain supplies for hunters to drop off a deer head with 5 inches of neck attached.
* A helpful video tutorial [ [link removed] ] is available to show you how to submit your sample information using the online form.

* *In-person with cooperating partners:* Meat processors and other businesses can collect the deer head for sampling or remove the lymph nodes at the time of drop-off. This is a convenient option for hunters who intend to mount their deer.
* If a taxidermist is not a cooperator, ask for the caped-out head back to submit at a kiosk.

* *At-home lymph node extraction: *Hunters may pick up a kit from a kiosk ahead of time, extract the retropharyngeal lymph nodes using the provided instructions and return the lymph nodes to the DNR or a kiosk for testing.
* Follow the printable step-by-step instructions [ [link removed] ] to extract lymph nodes and prepare them for testing.

* *By appointment with local DNR staff:* Hunters can contact their local wildlife management staff to schedule an in-person appointment. Please note, the availability for these appointments is limited.

CWD results will typically be available within 1-2 weeks. Hunters can find the nearest location using the DNR’s CWD Sample and Disposal Locations map [ [link removed] ].  

*Replacement Harvest Authorizations  *

A reminder, if a hunter receives a CWD-positive test result, a replacement authorization will be issued to their Go Wild account [ [link removed] ] within 2-4 days from notification. A positive result from an antlered harvest authorization will result in a replacement antlered harvest authorization for the hunter (valid statewide). If the positive result was received for an antlerless harvest registration, an either-sex replacement harvest authorization will be issued for the same DMU and land type. 

The replacement authorizations aren’t weapon-specific and are valid for the remainder of the current hunting season and next year's hunting seasons (starting in September 2026).  

*Carcass Disposal Reminders*

Proper disposal of deer carcasses can reduce the chance of CWD being introduced to a new area. Several disposal resources are available for hunters, including deer carcass waste disposal dumpsters, landfills or transfer stations. These options can be found on the DNR's CWD Sample and Disposal Locations map [ [link removed] ], and the DNR encourages hunters to check the map again throughout the season.

More dumpsters will be added closer to the nine-day gun hunting season. Hunters may also be able to dispose of carcass waste in curbside pickup for residents. Contact your local solid waste provider or municipality to check carcass waste acceptance policies before disposal.

*Baiting And Feeding *

Hunters should also be aware of current baiting and feeding bans by visiting the DNR’s Baiting and Feeding webpage [ [link removed] ]. There are two counties with new bans in place since last year’s hunting season: Manitowoc and Clark counties. 

The DNR’s Chronic Wasting Disease webpage [ [link removed] ] provides more information about baiting and feeding bans, testing options and disposal options.

*Consuming Venison*

The Wisconsin Department of Health Services (DHS), the Centers for Disease Control and Prevention and the World Health Organization all recommend against consuming meat from deer that test positive for CWD. Infected deer typically appear healthy for many months after contracting the disease, so DHS encourages testing for the disease regardless of the physical condition of the harvested deer, especially in areas prevalent with CWD [ [link removed] ]. To date, there have been no reported cases of CWD infection in humans.
